CONDUCTOR.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed October 15, 1997. Serial N 0. 357,486.

To all whom it may concern:

Be it known that I, GEORGE W. BOLTON, Jr., a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Conductors, ,ofwhich the following is a' specification, reference being bad therein to the accompanying drawings.

The invention relates particularly to a conductor tip especially designed in thisinstance for engagementwith a binding post, such-as abattery, terminal, and it consists in the novel and peculiar construction of the tip and in the particular arrangement and combination of the various parts, as more fully hereinafter set forth. 1

In the drawings-Figure 1 is a perspective view of the conductor tip applied to a battery terminal; Fig. 2 is an enlargecl plan view of the attaching section blank and a portion of'the body member of the tip; Fig. 3 is a vertical central section through the formed blank, showing the connection with the conductor; F i 4 is aside eleva tion of. the tip; Fig. 0 is a modification; and Fig. 6 is a further modification, illustrating a different type of binding post.

For the purpose of illustrating the invention I have shown the conductor of a length to connect two adjoining battery terminals, the terminalbeing of the usual form, consisting of a-threaded shank, as A, and the binding post head B in the form of a thumb nut.

C represents a conductor, comprising the wire or conductor proper a and the insulation I), and I) indicates the tip.

In'construction, the tip comprises an attaching section E, preferably n the form of a tubular shank adapted to-engage over the conductor end and have a suitable connection witli.the' conductor proper, and a body section F, preferably loopshaped in configuration.

InFigs. 1rd 3 I have shown the body and attaching section as formedin separate arts, the attaching member being formed om a blank, as a, notched transversely on opposite sides, as at (Z. The body member when used inconnection with the attaching section. described may be made of spring wire, bent into form as shown in the figures referred to and the ends secured by means of the lips e, which are bent upwardl and about the' adjoining ends 1 of the b0 y, as

plainly shown in Fig. 3. The marginal portions 9 of the body blank are adapted to be bent upwardly and over the conductor C,

the conductor wire being first folded inwardly and rearwardly so as to contact with the attaching section in the manner indicated in Fig. As thus constructed, the attached member not only forms a means for holding the body ends together in their proper position, but also the connection between the body and the insulated conductor.

In construction, the tip body is so fashioned as to form-an openin la of a size to receive the head of the binding post or battery terminal, a smaller opening 2' beyond the opening 71, and a restricted passage j, uniting the two openings, formed by converging the opposlte sides of the body at opposite'points intermediate the body ends. As thus constructed, the body may be placed directly over the head of the nut 13, and then by drawing the tip the neck or shank of the nut may he brought within the opening '1', the sides of the body being necessarily sprung apartas the neck of the nut passes through the restricted opening or passage; Thus, the body automatically clamps the battery terminal, and in addition to permitting a ready engagement between the parts forms an effective electrical contact.

For the purpose of effecting a still better I engagement between the parts, I so fashion the body that it will be provided with a.

plurality of contacting portions lying substantially in the same plane, adapted'preferably to engage the under side of the nut head, and similar contacting portions lying in a difi'erent plane from the first-mentioned contacts, but in substantial parallelism thereiwith, adapted to engage the lower portion of the nut, as hereinafter set forth.

The several contacts described are made preferably by forming in the end of the tip body distant from the shank a transverse trough-shaped depression, as H (Fig. 4:).

As thus fashioned, contacting portions I and J -are formed in substantially the plane of the body, as indicated, and similar contactin portions K in a different plane, substanticilly'in parallelism with the body.

The portions I and J, as shown in Fig. 1, engage beneath the nut head and contact therewith, while the contacting portions K extend below the other contacts in engagement with the neck portion of the nut, the several contacts cooperating to hold the head members of the tip tightly engagement with the binding post, thus forming the desired contact and at the same time permitting the ready disengagement of the parts.

In Fig. 5 I have shown a modified form of tip, in which the attaching-section L and body member M are formedfrom a single piece of metal. /Viththis difference, the tip is practically of the same construction as that heretofore described.

While I have shown the tip as adapted to be looped over the nut of the battery termi nal, or the head portion, of any'biiiding post,

thus permitting ready contact to be made, it

is to be understood that if desired the body portion of the tip may be so proportioned as to engage the stem 01' threaded shank otthe battery terminal in the same manner as the nut proper, the converging of the body sides causing the tip to clamp the shank and form the desired contact.

In the modification illustrated in Fig. 6, the tip isshown as formed of a heavier metal and the body sides made independent of one another by cutting the loop or body portion at its extremity, as indicated at a. In this form of tip, the sides are sprung apart asthe neck orshank of the binding post passes through the restricted passage, and automathead of the screwan'd contact made with the Y screw shank in the manner previously set iorth.

W hat I claim as my invention is,

1. In a conductor ,tip, an open-centered body having longitudinally disposed contacting portions lying in substantially the aa the body, and a contacting portion intermesame plane, and a contacting portion intermediate the first-mentioned contacts and lying in a different and substantially parallel plane therewith.

- 2. Aconductor tip, comprising an attaclr ing section and an open-centered body of spring-metal having spaced longitudinally- "sposed contacting portions in-a plane of diate the spaced portions and lying in a different plane parallel with the body.

3. A conductor tip, comprising an attaching section adapted to be secured to the conductor,'and a substantially flat loop-shaped body'member having a transverse troughshaped depression formed in its end portion distant from the attaching section. V

4. A conductor tip, comprising an attaching section anda loop-shaped-body of spring metal, the body sides at opposite points intermediate the ends converging and the loop end distant from the attaching section and beyond the diverging portion having a transverse trough-shaped depression formed therein. V I

5. A conductor tip, comprising a tubular shank section and an open-centered body alining with the shank, and having a trough shaped depression formed transversely therein.

6. A conductor tip, comprising a tubular shank section adapted toreceive the conductor, and a loop-shapedbody member of spring metal, the loop sides at opposite points intermediate the ends converging, and the portions of the sides therebeyond having each a trough shaped depression formed transversely therein, for the purpose de scribed. 1

7. A conductor tip, compris ng an attaching section and an open-centered body having a trough shaped depression. formed transversely therein.

- 8. A conductor tip, comprising an attach: ing section, and a body of spring metal having an elongated opening formed therein and its end distant from the attaching section upturned.

9. A conductor tip, comprising an attaching section, and a body Otspr ng metal provided with an opening ad oining the attaching section, and a communicating opening.

beyond and of less size than the first-mentioned opening, the bodyhaving an upwardly extending contacting portion formed therein beyond said fii'st-nientioned openl'n testimony whereof I afiix my signature in presence .of two witnesses.
